Description
Lirah-1 is an osc unit based on James D. Cheetham's Lyre-1 project, inspired by the SOMA Laboratory Lyra-8. Knob A sets FM depth and knob B sets the depth of the Hyper LFO pitch jump, which comes from two internal LFOs that are AND-gated. Further parameters cover both LFO rates, fold, FM and carrier tuning, feedback, and a third LFO with a selectable target. It is sold on Gumroad (listed at 5 USD) with the source and a release on GitHub. A 4-voice polyphonic drumlogue version is in DanielMajid/lirah_4_drumlogue, which has no license file.
